Thanks for the reply Frank,
Been out and about in the Micra again, the temp seems to be bouncing up and down between H and the middle. For the last few miles it seem to be very high, when I got back whilst there wasn't any spitting from the reservoir there was the sound of bubbling again coming from the top hose.
Can't think of much else that's would be causing this other than the thermostat.... so any recommendations if I do it myself?
Thanks.
